Leave it to Japan to fiddle with the adult diaper technology and develop the next-generation space toilet. The Japan Aerospace Exploration Agency (JAXA) has teamed up with engineers from the private sector to complete the project in the next five year:

Clean and easy to use, the envisioned space toilet is designed to be worn like a diaper around the astronaut’s waist at all times. Sensors detect when the user relieves him or herself, automatically activating a rear-mounted suction unit that draws the waste away from the body through tubes into a separate container. In addition to washing and drying the wearer after each use, the next-generation space toilet will incorporate features that eliminate unwanted sound and odor.
